“…This location and its fringing intertidal reefs have been described in detail (Scoffin et al 1992;Brown et al 2011). At this site, all colonies of the merulinid coral C. aspera are subaerially exposed to air at low water on the inner reef flat for 2-3 h, and none are found in tidal pools or fully submerged.…”

Shifts in the microbiome of the intertidal coral Coelastrea aspera (formally known as Goniastrea aspera) from Phuket, Thailand, were noted over the course of a 4-d period of spring tides. During this time, corals were naturally exposed to high temperatures, intense solar radiation, sub-aerial exposure and tidally induced water fluxes. Analysis of the 16S microbiome highlighted that the corals harbored both 'core or stable' communities and those which appeared to be more 'transient or sporadic.' Only relatively few microbial associates were classified as core microbes; the majority were transient or sporadic. Such transient associates were likely to have been governed by tidally induced variations in mucus thickness and water fluxes. Here we report strong shifts in the bacterial community of C. aspera over a short temporal scale. However, we also show significant differences in the timing of shifts between the two age groups of corals studied. More rapid changes (within 2 d of sub-aerial exposure) occurred within the 4-yr-old colonies, but a slightly delayed response was observed in the 10-yr-old colonies, whereby the microbial associates only changed after 4 d. We hypothesize that these shifts are age related and could be influenced by the observed baseline differences in the microbiome of the 4-and 10-yr-old corals, bacteria-bacteria interactions, and/or host energetics.

“…These differences may be explained by variations in framework accommodation space (Fig.2), in the spatial distribution of 'direct sediment' and 'framework' production across the reef zones (Fig. 4a), in processes of sediment-particle production (Chave 1964) and taphonomic processes (Scoffin 1992), in particular transportability (Folk and Robles 1964;Maiklem 1968), and by spatial separation between carbonate production and sediment-deposition zones Purdy and Gischler 2005).…”

“…2) and, thus, potential for carbonate to be retained as framework. And, although not well quantified, coral has high durability properties related to its architecture (Chave 1964;Folk and Robles 1964;Scoffin 1987), implying relatively-slow conversion rates to sediment, contributing to the dilution of coral in surficial sediments by organisms with higher turnover and sediment-conversion rates (Scoffin 1992).…”

“…Minimum and maximum estimates of 60 and 250 g m -2 yr -1 of calcification per 15% cover (400 and 1,667 g m -2 yr -1 for 100% cover) were used to test the sensitivity of the total carbonate production figures to Halimeda production rates, taking into account potential variation in local growth rates and in the exact ratio of rhipsalian to lithophytic species present in the different reef flat subenvironments.

Complex relationships exist between tropical reef ecology, carbonate (CaCO 3 ) production and carbonate sinks. This paper investigates census-based techniques for determining the distribution and carbonate production of reef organisms on an emergent platform in central Torres Strait, Australia, and compares the contemporary budget with geological findings to infer shifts in reef productivity over the late Holocene. Results indicate that contemporary carbonate production varies by several orders of magnitude between and within the different reef-flat sub-environments depending on cover type and extent. Average estimated reef flat production was 1.66 ±1.78 kg m -2 yr -1 (mean ± SD) although only 23% of the area was covered by carbonate producers. Collectively, these organisms produce 17,399 ±18,618 t CaCO 3 yr -1 , with production dominated by coral (73%) and subordinate contributions by encrusting coralline algae (18%) articulated coralline algae, molluscs, foraminifera and Halimeda (<4%). Comparisons between these organisms production across the different reef flat zones, surface sediment composition and accumulation rates calculated from cores indicate that it is necessary to understand the spatial distribution, density and production of each major organism when considering the types and amounts of carbonate available for storage in the various reef carbonate sinks. These findings raise questions as to the reliability of using modal production rates in global models independent of ecosystem investigation, in particular, indicating that current models may overestimate reef productivity in emergent settings.

“…The polyp generates the carbonate skeleton with annual banding, and lives on the surface of the skeleton [7]. The deposition characteristics of coral carbonates accumulating in the skeleton make the coral function as a chronometer [8,9], in the same way as tree rings and speleothems (including stalagmite, flowstone, etc.). The formation of biogenic aragonite layer is impacted mainly by sea temperatures and the ocean environment [10], which is the reason that Porites coral can become a recorder of changes of climate and environment.…”
